It should be noted that the bed leg sections are selected according to customer needs to meet the height adjustment of the bed frame, and thus the bed leg can have one leg section, or three or more leg sections. Each of the multiple leg sections has the same size or a different size.

Each leg section 110/120 comprises a central column 111/121 and a decorative shell 116/126 configured to detachably sleeve on the central column 111/121, as shown in FIGS. 2-3 and 10.

In some embodiments, the central columns 111 and 121 of the first leg section 110 and the second leg section 120 are essentially same. In other embodiments, the central columns 111 and 121 of the first leg section 110 and the second leg section 120 are substantially same, except that the lengths of the central columns 111 and 121 may be different. In some embodiments, the outer diameter of each central column 111/121 is same. For the concise purposes of illustration and description, the following description of the central columns is particularly referred to the central column 111. It should be noted that such description is also suitable to the central column 121.

The central column 111 has a first end, an opposite, second end, a connecting bolt 112 attached to the first end, as shown in FIGS. 4-5. The central column 111 also has a bolt hole 114 formed in the second end, as shown in FIGS. 5-6. The central column 121 may also have a bolt hole formed in the second end, or may not have a bolt hole formed in the second end if the central column 121 is a central column of the very last leg section.

As shown in FIGS. 4-6, in some embodiments, the central column 111 comprises a hollow tubular structure, which can reduce the weight of the bed. The central column 111 has first and second covers 113 and 115 respectively attached to the first and second ends of the central column 111. The connecting bolt 113 and the bolt hole 114 are respectively arranged on the first and second covers 113 and 115. The central column 111 in some embodiments can be cut from a steel pipe. The covers 113 and 115 can be clamped in the cut steel pipe or welded onto the cut steel pipe. The covers 113 and 115 are arranged to facilitate fixing of the connecting bolt 2 and the setting bolt hole 61, which is convenient for the installation of the bed leg and the bed frame, and also for the connection of multiple leg sections.

In some embodiments, the decorative shells 116 and 126 of the first leg section 110 and the second leg section 120 are essentially same. In other embodiments, the decorative shells 116 and 126 of the first leg section 110 and the second leg section 120 are substantially same, except that the lengths and the outer diameters of the decorative shells 116 and 126 may be different. For the concise purposes of illustration and description, the following description of the central columns is particularly referred to the decorative shell 116. It should be noted that such description is also suitable to the decorative shell 126.

The decorative shells 116 and 126 can be designed to have an exterior shape in a form of a cylinder (or round column shapes, not shown), a cylindrical cone (or truncated cone shapes, FIGS. 1-3, 7 and 10), a polygonal column (prismatic shapes, FIGS. 13-16), or any desired curve shapes. In addition, the exterior surfaces of the decorative shells can include different patterns or drawings. Furthermore, at least one of the decorative shells may include lighting members such as light emitting diodes (LEDs) for providing night light.

In some embodiments for cylinder type decorative shells, an outer diameter of the decorative shell of each of the two leg sections 110 and 120 is same. In other embodiments for cylindrical cone type decorative shells shown in FIGS. 1-3, 7 and 10, an outer diameter of the decorative shell of each of the two leg sections 110 and 120 is different.

In some embodiments, the decorative shell 116 comprises a double-layer tubular structure having an inner layer 117 and an outer layer 118, and connecting ribs 119 arranged between the inner and outer layers 117 and 118 of the double-layer tubular structure, as shown in FIG. 7. The design of the double-layer structure can reduce the weight, and strengthen its stability through the connecting ribs 119. In this embodiment, the inner tubular sleeve layer 117 is tightly fitted with the central column 111, and the outer tubular sleeve layer 118 is used as a shape carrier. Different shapes, such as a cylinder, a cylindrical cone, or a polygonal column, can be designed.

In some embodiments, the decorative shell can also be a single-layer tubular sleeve structure, which is designed on the outer peripheral surface to realize different geometric shapes as a whole.

In some embodiments, the decorative shell is formed in a single piece, as shown in FIGS. 1-3, 7-8 and 10-12.

The assembly and disassembly of the bed leg are very easy. In one embodiment as shown in FIG. 11, one can place the first and second central columns 111 and 121 into the first and second decorative shells 116 and 126 to obtain the first and second leg sections 110 and 120, respectively, and then connect the first and second leg sections 110 and 120 by tightening/screwing the connecting bolt of the second central column 121 of the second leg section 120 into the bolt hole of the first central column 111 of the first leg section 110 to have the bed leg 100 assembled. Reversed procedures lead to disassemble the bed leg 100. In another embodiment as shown in FIG. 12, one can screw the connecting bolt of the second central column 121 of the second leg section 120 into the bolt hole of the first central column 111 of the first leg section 110, and then sleeve the first and second decorative shells 116 and 126 on the first and second central columns 111 and 121 to have the bed leg 100 assembled. Reversed procedures lead to disassemble the bed leg 100.

Referring to FIGS. 13-16, a bed leg 200 is shown according to another embodiment of the invention. The beg leg 200 is substantially same as the bed leg 100 shown in FIGS. 1-12, except that each decorative shell 216/226 is formed in a shape of polygonal columns with multiple pieces, e.g., two pieces 216 a/226 a and 216 b/226 b. In this exemplary embodiment shown in FIGS. 13-16, the polygonal column is a square column or a slanted square column. In other embodiments, the polygonal column is a pentagonal column, or a hexagonal column, and so on.

In one embodiment, at least one (e.g., the decorative shell 216) of the decorative shells 216 and 226 includes a lighting member 219 such as LEDs for providing night light, as shown in FIG. 14. Also referring to FIG. 14, at least one (e.g., the decorative shell 226) of the decorative shells 216 and 226 may also include a pattern 218, or drawings.

The multiple pieces 216 a/226 a and 216 b/226 b are configured to detachably attach to one or another by mate-female connecting means or the likes. Such design of the decorative shells makes a user to replace or change the appearance of the bed legs of the bed even much easier.

Similarly, the assembly and disassembly of the bed leg according to this embodiment are also very easy. In one embodiment as shown in FIGS. 13-14, one can attach the first and second pieces 216 a and 216 b of the first decorative shell 216 to the first central column 111 to assemble the first leg section 210, and the first and second pieces 226 a and 226 b of the second decorative shell 226 to the second central column 121 to assemble the second leg section 220, respectively, and then connect the first and second leg sections 210 and 220 by tightening/screwing the connecting bolt of the second central column 121 of the second leg section 220 into the bolt hole of the first central column 111 of the first leg section 210 to have the bed leg 200 assembled. Reversed procedures lead to disassemble the bed leg 200. In another embodiment as shown in FIG. 15-16, one can screw the connecting bolt of the second central column 121 of the second leg section 220 into the bolt hole of the first central column 111 of the first leg section 210, and then attach the first and second pieces 216 a and 216 b of the first decorative shell 216 to the first central column 111, and the first and second pieces 226 a and 226 b of the second decorative shell 226 to the second central column 121 to have the bed leg 200 assembled. Reversed procedures lead to disassemble the bed leg 200.

In some embodiments, the central column and the decorative shell are made of a same material or different materials. In some embodiments, the central column is made of a metallic material, e.g., aluminum, steel, or an alloy. In some embodiments, the decorative shell is made of a plastic material, or a wood material.

As shown in FIGS. 17-18, the bed legs (e.g., legs 100) can be easily installed on the bed (e.g., bed frame 101 with bolt holes) by simply tightening/screwing the connecting bolt of the first central column of the first leg section of each bed legs into a corresponding bolt hole, or detached the bed legs 100 from the bed by the reverse procedure.

According to the invention, the bed legs have the decorative shells designed in desired shapes and even with different patterns that can meet the different needs of different customers for external shapes, which can be of truncated cone, prismatic or other curved shapes, thereby bringing customers different aesthetic experience. In addition, when assembling, only need is to tighten the connecting bolt 2 with the bed frame. The height of the bed legs can be selected according to the needs, which can be one leg segment/section, or two or more leg segments/sections.
